Abstract
Processes for starting up and operating anaerobic, deep tank fermentation reactors including a process for anaerobic bioconversion of a gas substrate comprising carbon monoxide, hydrogen, and carbon dioxide in a reactor by contact of the gas substrate with an aqueous menstruum containing microorganisms suitable for converting the gas substrate to an oxygenated organic compound in the reactor. The process further includes: blanketing the reactor above the aqueous menstruum to the essential exclusion of oxygen with a head space gas comprising at least one of carbon monoxide, hydrogen, carbon dioxide, nitrogen, and a lower alkane; continuously supplying a feed gas comprising at least a portion of the gas substrate to the aqueous menstruum in the reactor; and injecting the gas substrate and a motive liquid into the reactor to form a dispersion of the motive liquid and microbubbles, the microbubbles having a diameter of less than about 500 microns.
